Replace operating system after replacing dead HD

Pavilion dv7-4285.  I am replacing a totally dead Hard Drive! How do I get (free, oe cheap) replacement for Operating system. I did not receive software disks from retailer.
This question was solved.

Hi,
There are two options available.
1.  You can order a replacement set of Recovery Discs using the link below - these will reinstall the operating system, all required drivers and nearly all of the original software ( the exception often being trials of MS Office ).  They will also re-create all the original partitions, including the Recovery Partition.
Order HP Recovery Discs.
2.  Another option you could consider is to create your own Windows 7 installation disc.
Before trying the following, make sure you can still read the 25 Character Product Activation key on your Windows COA label ( 5 blocks of 5 alpha/numeric sets ).
An example of a COA Label can be seen Here.
You can create a Windows 7 installation disc yourself using another PC - just download the correct Disc Image ( this must be the same version that originally came with your notebook - this is listed as Windows 7 Home Premium 64bit ) from the link below and use an application such as ImgBurn ( Note: You may want to de-select the additional software offerings during the installation of ImgBurn ) to burn the ISO correctly to a blank DVD - a guide on using ImgBurn to write an ISO to a disc is Here.  The Windows Image source is Digital River.
Windows 7 Home Premium SP1 64 bit.
Use the disc to perform the installation, enter the Windows activation key found on the COA Label when requested and when the installation has completed, use the 'Phone Method' detailed in the link below to activate the OS - this method supported by Microsoft and is popular with people who just want a clean installation of Windows 7 without the additional software load normally bundled with OEM installations.

  • HT1752 i need a powerbook g3 400mhz operating system to replace the crashed one.

    hi, i have a powerbook g3 400mhz laptop and lots of data on the harddisk. The system shows an error and a bomb and then freezes.
    I tried all key combinations to restart but to no avail. Also I lost the original operating system disks. How can I save my data or install a fresh operating system. please help.

    Buy OS 9 or obtain it, then put it into the CD drive and boot from it. You should then be able to recover your data.

    I wanted to have the SSDs in RAID0 with Win7 and the games on it, then a volume on the 2TB that the RAID backs up to, with the remaining 1.5TB just free storage space in another volume.  I couldn't get raid past Win7's Where Do You Want To Install screen during installation, so I ended up installing the OS on just one SSD.  I figured I'd backup the functioning OS to the 2TB then rebuild the RAID array and copy the OS back onto it.
    The system had been up an running for a full day, being updated left and right nonstop, several big games put in, etc etc, everything was running fine until I decided to run MSI Live Update and started pumping in updates.  Constant errors as I went along, but generally it'd just skip to the next installation attempt.  When it got down to updating the BIOS and did it's DOS injection thing, it for forcefully shut down the PC, restarted, did Post, flashed the BIOS wallpaper, restarted again, Posted, no BIOS wallpaper, just endless "Missing Operating System".  Walked away, went to bed, back up and at it for a few minutes (Will be back tonight for however long it takes to get it fixed).  I switched the BIOS switch over, no dice.  Feels like it's a BIOS "OS" that's gone, and that a BIOS reset/flash is in order or something, but I've never done these things.
    Thanks in advance for any rendered assistance that leads to resolution.

    The SSDs are definitely hooked up where they're supposed to go; the motherboard had a little sticker n' everything for where the two SSD dedicated SATA 6.0gbps ports were :P  AND my case has 2 specific slots for SSDs which don't use the hotswap electronics PCB passthrough like the other 4 bays, which is where the 2T is installed.  I was going to take the 2TB out and hook it up normally and see if that changed the speeds, but I'm leaning towards wishful thinking.  Did I mention I went and made several volumes with different file cluster sizes to test and see if that was the issue?  Alas, all were borked.  It still confuses me though because every once n' awhile it'd do massive burst speeds the way it's supposed to.
    As far as I can recall I'm using up to date BIOS, the last one or two.  One BIOS switch is set for the last BIOS, the other switch is a step back devoid of the Windows 8 stuff.  I believe I have all the drivers up to date as well.  Intel 335's are literally brand new, mine hadn't been more than 3 weeks old off the production line when I received them; IE, they should pretty much have the latest firmware on them which spares me the risk of destroying something precious 
    I MIGHT have a SATA external enclosure around here somewhere, if so, the 2TB could go in that for additional testing until I figure out where it's sustaining speeds of 2-10MB vs 100-150MB/second.
    Meanwhile, the good news is that the system has been fully operational and hella stable.  I hadn't slept in almost 3 days, playing and installing stuff nonstop.  The system continues to run cooler (32c@stock CPU speed) as the thermal paste sets in, the knocking sound of the fan in the PSU has gone away upon me reawakening a bit ago, and amazingly, this massive system (with EIGHT fans) draws only 60-65 watts while desktopping.  That's just astounding 

  • How do I reinstall my operating system after hard drive upgrade on MacBook pro?  I have Snow Leopard install disc

    How do I reinstall my operating system (Snow Leopard) after a hard drive upgrade. I did a Time Machine backup before the new hard drive was installed. I put in the Snow Leopard install disc and don't get the icon I'm supposed to double click to install Snow Leopard and then the backup.
    HELP PLEASE!!

    Is the new HHD in the MBP?
    Is the new HDD formatted Mac OS Extended (Journaled)?
    Where is the old HDD? In an enclosure?  What is on the old HDD, your user data?  Is the Snow Leopard System on it?
    Do you have a separate Time Machine Disk with your user data?
    Answers to these questions should give an exact status of your situation so that one can proceed in the right direction.

  • HT1222 Non responsive operating system after this most recent update?

    About 5 days ago, my computer randomly decided to shut off without warning. The next day, Safari caused my computer to crash if I had it open for more than 30 seconds. That night, the operating system could hardly take a terminal command without acting like it had 1MHz clock speed.
    I have freshly installed Mavericks again on my MacBook 5,1... After reloading a time machine storage of a month old, exactly the same thing happened. Everything is colossaly slow.
    I am now on my second fresh install of Mavericks, and I dare not reload my time machine backup... No problems as of yet.
    Ill come back to this post after I install the HT1222 update again, and reply if I see the same problems again.
    Not impressed with the update.

    Welcome to Apple Discussions!
    When I press the power button, the computer simply beeps three times and does nothing else. I can't get the computer to start up using a system disk either.
    That says your logicboard or RAM went bad. It has nothing to do with the security update.

  • T61: "Error loading operating system" after reboot with Windows XP SR3

    So here is my problem:  Occasionally, after reboot I get "Error loading operating system" right after the Lenovo screen (the one where you can press ThinkVantage button). After that the only thing I can do is shut down the computer and fix the windows boot (see bellow…). I'm running Windows XP SR3, clean install.
    I've had my T61 for 6 months now and I've had this problem about 8 times so far. Obviously this makes my T61 unstable and is becoming a major problem (I like to shut down the computer before taking it anywhere, and I don't really use Hibernate).
    Solving the boot is very easy and takes 3 minutes… But the Win XP CD is needed for the fix and I don't want to carry it around with me everywhere. And anyway this is annoying and makes my T61 crippled…
    To fix the problem:
    1 Change AHCI -> Compatibility in BIOS.
    2 Boot using the Windows XP CD.
    3 Enter the Recovery Console (press R).
    4 Use "fixboot" to write a new boot sector.
    5 Restart ("exit").
    6 Change back to AHCI in Bios.
    After that the computer works perfect until the next time… Things I have tried so far:
    1 Installed latest Bios for T61.
    2 Checked firmware for HD (WD Scorpio WD1600BEVS) and it's the latest.
    3 Installed all windows updates for Windows XP.
    4 Installed all latest drivers for T61 (specifically checked the Intel Matrix Storage Driver and it's the latest).
    5 Checked computer for Viruses, malware, etc. with a few scanners. It's clean.
    6 Updated some of the programs that I thought might be causing problems: Avira , PerfectDisk 2008, TrueImage Home…
    7 Checked HD with WD Diagnostics tools
    I am out of ideas. Something is corrupting the boot sector occasionally when I shut down the system. But I can't find why or under  what circumstances it happens… The only thing I didn't try was a completely new clean system install, a thing which I REALLY don't want to do. Except for this problem the system is great, very stable and I'm very happy with it.
    Any ideas? Thanks in advance.

    I run the windows version of TestDisk. Is there any specific reason for me to make a Live CD? It seems to work just fine in windows. Anyway, I run all the analysis tests with it. It did NOT find any problems. Is there some specific test I should run?
    Some further testing has shown me that the problem happens sometime during using windows and not upon restarting... When it does happen I can no longer use chkdsk - it gives the following error message:
    "The type of the filesystem is RAW.
    CHKDSK is not available for RAW drives."
    Some other things I tried:
    - I've pretty much ruled out physical HD problems (I checked the HD with PC Doctor, WD's Data Lifeguard Diagnostic Tool and chkdsk - no problems). And the HD shows no symptoms of failure (no noises or any other problems).
    - Ruled out boot-sector Viruses (cheked the computer with 4 different antiviruses - Avira,AVG, Kaspersky and NOD32).
    - Manually checked the boot.ini file - no problems.
    - I have also found while googling that the problem might have to do with a registry entry concerning HDs bigger then 137gb. I double checked that entry and it's fine.
    - Tried both fixmbr and fixboot, alone and together - windows boots, but the problem comes back again after a few hours/days...
    Things I'm trying now:
    - Reinstalled the Intel Matrix Storage Drivers (before I just checked that they are the latest).
    - Disabled the Active Protection System (I am shooting in the dark...).
    I am getting pretty desperate here.

  • Error loading operating system after installation of Linux AS4

    Hi,
    I have Hardware HP DL580 G3 server attached with SAN.
    I just installed Linux AS4, installation went fine and successufly installed, upon rebooting of server it is giving following error.
    attempting from Hard Drive (C:)
    Error Loading Operating system
    Please help me out

    First: did you install the bootloader in the MBR (it's a question during the installation), so the server is able to boot linux automatically?
    "C:" is a typical MSDOS naming (and windows naming), which probably means the dos/windows bootloader is still in the MBR (master boot record)
    If not, reinstall linux and install grub (preferably) in the MBR

  • Can I restore my system after replacing my hard drive with the original leopard discs, then use my time machine backup (with Snow Leopard) to finish the restore?

    I am replacing my original 100gb hard drive for a 500gb.  I am currently running OS X.6.7.  I understand the process of how to install the new drive and restore the system from the disc.  What I am unsure of is whether I need the Snow Leopard disc or can I use the original Leopard discs and then plug in my time machine backup to complete the restore?

    How do I restore my entire system?.
    or, use Carbon Copy Cloner to clone your current system to an external HD, replace the HD, then clone the clone back to the new drive.

  • How do I restore my Mac operating system after a botched uninstall of Bootcamp.

    I completely botched up uninstall of Bootcamp.I wanted to uninstall and delete Windows 7 and re-do the operation. Bootcamp did not manage an uninstall and I got put back into a Widows install operation.Which won't re-install because it can't fiind a suitable hard disk. I have 4 sata harddrives installed, one contains the Mac OSX system files, one a Timemachine backup and one the Windows system.Other is data.
    I have a boot USB. None of the startup keys (Press C during startup,Shift key, Cmd R ete) will respond.The machine just behaves like it has a windows BIOS and won't allow any way to see any of the Mac files.Nor will it accept any HD to try a reload of windows. I've tried replacing the data drive with a spare formatted for NTFS, but the Windows setup file won't proceed far enough to enable this to be tried. Any help. I just want to get back to running OSX again.

    Have you tried press and holding the option/alt key while starting up so as to get the startup manager screen. I think you have too many drives attached for Boot Camp to install. Are these on the MacBook Pro you have listed?

  • Problems with 10.3.9 operating system after upgrades

    I recently downloaded a system update and am having problems.
    I can no longer print. Printer error.
    Also, I tried to download an HP Laserjet 5000 driver to see if that would fix it, and I couldn't install, as I tried to install with my system password and it said I need an Adminstrator level or higher to install???
    Any help please.

    Powerbook 17   Mac OS X (10.3.9)  

    My Dad (age 86) has encountered what I am almost positive
    is this precise problem. He downloaded some kind of
    security patch around Jan 26 and all his (3) printers
    got disabled. He is running MacOS 10.3.9 on a PPC
    Mac. I've been through the article on creating
    /var/spool/cups with him. We've done "Repair
    Disk Permissions" in Disk Utility. It still doesn't
    work. When he does "Add Printer", he gets all the
    way through to the step of manually selecting the
    Printer Description and then he gets
    server-error-service-unavailable
    Is there a way to get the equivalent of the Tiger
    feature "Reset printing system" in Printer Setup
    on 10.3.9? I think that's what he needs to do.
    Are the steps documented anywhere?
    Or does anyone have other suggestions? I thought
    about running "Repair Disk" in Disk Utility, but
    my conclusion from reading the documentation is
    that this is morally equivalent to "fsck" in
    regular Unix. That is, it only checks the
    structural integrity of the file system itself.
    It has no idea of the files required by a particular
    subsystem.
    The only other thing I can think of to do is to
    reinstall 10.3.

  • Boot Device Not Found Please Intall an Operating system on your hard disk. Hard Disk - (3F0)

    Hello,
    I tried to re-install de OS from windows 7 to windows 8.1 and when the bios update driever was installed and the laptop was restaring it appeared the folowing window and message:
    Boot Device Not Found Please Intall an Operating system on your hard disk. Hard Disk - (3F0)
    After that i tried a lot of different ways to get to boot device select ...but i couldn't do anything. I removed the HDD and i put it back, i've tried with holding in the same time windows +B and pressing the power button in the same time for 1..2 seconds and then i've waited for at least 1 minute..and it didn't appeared anything on the screen. I've done the hard drive check and it passed. The weirdest thing is that when i want to select a boot device to re-install again the OS, i can't see any boot device to select. I need to mention that i've formatted the HDD in another computer. I dont care about the informations from the HDD beacause i saved all the informations on another device storage.
    Please help me repair this problem!!!  thanks a lot!
    Have a nice evening.!!!

    Whenever you get a message stating that the boot device not found it could be because of bad sectors on the Hard Drive. Its not necessary that the Hard Drive Test should fail to determine if the Hard Drive if its faulty or not. Sometimes even if the Hard Drive Test passes the Hard Drive will still not work because of the bad sectors in it.
    Best way to find out if its the Hard Drive you can try the Hard Deive on a different Notebook which would help you determine if it's faulty or not.
    Could be due to Application or driver conflicts, virus issues, file corruptions due to incompatible applications, improper shutdowns, update failures due to conflicts, sudden power surges, if notebook is dropped etc..
    HP will provide a replacement Hard Disk Drive if the Notebook warranty is Active, If not you need buy a SATA Hard Disk Drive from a retail shop nearby
    Please make sure you are getting at least equal capacity as the original one in order to use Recovery Disks. If you need you can buy a larger, but not smaller capacity Hard Disk Drive. For example if you have a 500GB Hard Disk Drive you can upgrade it to 750GB Hard Disk Drive but not 320GB Hard Disk Drive
    Please try the below shown troubleshooting steps once:
    Step 01. Remove the battery and unplug the AC/Power Adapter
    Step 02. Press and hold the Power button for more than 30 Seconds
    Step 03. Plug in the AC/Power Adapter (leave the Battery out for now)
    Step 04. Press the Power button and check if the Unit works normal
    If the above mentioned steps does not help, then you can try reseating the Hard Drive on your Notebook
    If the issue persists again please Contact HP if your HP Notebook is under warranty, HP would replace the Hard Disk Drive and provide you a Recovery media to restore factory operating system after replacement (if you've not yet created Recovery Discs/USB Media)
    Note: Back up all the personal data to an external drive if it's possible. Otherwise you could connect the failed HDD via SATA to USB adapter with another PC or same PC after replacement of HDD & re-installation of OS and try copying /recovering the files.

  • Can I revert back after upgrading to Mavericks operating system? Can't get my Adobe software to run properly.

    Can I revert back to a previous operating system after upgrading to Mavericks? Since installing Mavericks I can't get my Adobe software to run properly.

    Thanks, for your replies. I've got a late 2012 iMac (2.7 GHz Intel Core i5). I was previously running Snow Leopard - Not sure exactly what version but it was right up to date.
    The Adobe software I'm using is the Creative Cloud. Specifically InDesign cc. Whenever I try to browse folders through the InDesign software the browser window closes before I can do what I need to do. So I cant place images into my InDesign document or save documents properly.
    On the Adobe website it says that they worked with apple to fix any bugs before the Mavericks release but there's lots of complaints on the forums. I've left a bug notification with Adobe but I don't expect that they will be offering any solutions or software updates any time soon.
    I really just want to revert back without too much trouble.
